What Is Spline?

Spline is a browser-based 3D design tool in the design-toolscategory that provides a collaborative space for creating, editing, and publishing interactive 3D content. Operating on a freemium pricing model, Spline enables real-time teamwork without requiring desktop software installations, making it suitable for designers integrating 3D elements into web, mobile, and AR workflows. Users access familiar design interfaces to model, animate, and texture 3D scenes directly in the browser, positioning Spline within modern design pipelines that emphasize accessibility and team collaboration over traditional CAD complexity.

What Spline Does

• Supports 3D modeling with primitives, extrusion, beveling, and Boolean operations for creating custom shapes.
• Enables real-time collaboration, allowing multiple users to edit scenes simultaneously in the browser.
• Provides layer-based materials, including a library of ready-made options and custom layering for textures.
• Offers interactivity through states, events, timeline animation, physics, and particles for dynamic experiences.
• Integrates variables, real-time APIs, and webhooks to connect with data sources and AI for responsive 3D content.
• Allows multi-platform exports and embeds for web, iOS, Android, and other digital products without coding.

How Spline Can Be Used

Spline fits into design workflows for prototyping interactive 3D product visuals on websites, where teams model assets, add hover animations, and embed them directly. Developers use it to build AR previews or mobile app experiences by importing animated GLB or FBX files and refining interactions via events and physics. In agency settings, distributed teams iterate on 3D scenes in real-time, applying textures and data-driven changes via APIs for client feedback loops. Product designers create contextual UIs that respond to AI-generated content, exporting to native apps across Android and iOS ecosystems.

• Remixing community scenes to learn modeling and animation techniques.
• Prototyping scroll-triggered 3D models for landing pages with lighting and shadows.
• Building physics-based interactions for game-like web experiences.

Who Is Spline For?

Spline serves designers, developers, and product teams working on interactive 3D for web and apps, particularly those transitioning from 2D tools without prior 3D expertise. It supports creative professionals in startups and agencies handling remote collaboration on prototypes, AR content, or data-integrated visuals. Experience levels range from beginners using its intuitive canvas to advanced users leveraging APIs and exports for production.Visit Spline
